DOT3-OAM-MIB
About this MIB
Ethernet Operation, Administration, and Maintenance (OAM) is a tool that monitors Layer 2 link status. It checks the connectivity of a link by sending OAM protocol data units (OAMPDUs) and reports to the network administrators when a link error occurs.
This MIB focuses on Ethernet OAM functions.
